The servo motor 94 drives the screw 93 to rotate through the synchronous belt transmission mechanism 95. The synchronous belt transmission mechanism 95 comprises two synchronous belt wheels 951 and a synchronous belt, wherein one synchronous belt wheel 951 is coaxially and fixedly connected with the screw rod 93; the other synchronous pulley 951 is coaxially and fixedly connected to an output shaft of the servo motor 94, and a synchronous belt is wound around the outer peripheries of the two synchronous pulleys 951.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
